Project Purpose To bring local governments, citizens, and businesses together to talk about growth issues To create a forum for local leaders to consider growth plans of their neighboring communities for regional mobility and prosperity To generate ideas for the 2035 Regional Transportation Plan, scheduled for adoption in 2010
Tri-County Regional Goals GOAL 1: Promote conservation of historic and cultural resources and support efforts in the study area related to these areas through plans, programs and policies. GOAL 2: Recognize and support the important role of agriculture in both the existing and future economy. GOAL 3: Preserve areas intended to retain a rural character or way of life and reinforce preservation through plans, programs, and policies.
Tri-County Regional Goals GOAL 4: Enhance economic growth and opportunities in the study area to ensure that a high quality of life remains for population in the study area. GOAL 5: Strengthen and enhance existing urban centers through plans, programs and policies. GOAL 6: Identify and protect the most critical natural resources that exist.
Tri-County Regional Goals GOAL 7: Provide for the efficient movement of persons, goods and services while providing a wide range of transportation choices for the study area. GOAL 8: Ensure that future growth in the study area occurs in a coordinated manner with community infrastructure and services needed to adequately support growth and development.
Tri-County Regional Goals GOAL 9: Provide a wide range of housing types and communities for a variety of household sizes and income ranges. GOAL 10: Allow new types of development while recognizing the importance of retaining the established character and existing development types unique to the study area.
UPDATED BUSINESS AS USUAL (BAU) SCENARIO
Purpose of BAU in Tri-County Study Show a continuation of plans, programs, adopted policy Regulations used if no policy Relationship to use of character types Assess impacts Assess if BAU represents a future that meets our regional goals? Community at Large sessions Sept-Oct 08
Results of Group Exercise Report Card on BAU Goals Historic Conservation and Enhancement Viable Agriculture Rural Preservation Economic Enrichment while Safeguarding Existing Public and Private Development Preserve Urban Centers Protection of Natural Resources Efficient Transportation System Ensure Availability of Services Provide Housing Options Maintain Sense of Community and Sense of Place Grade B B C+ B B B C B C+ B
Purpose of Character Types Allow land use pattern to be generally depicted Address multiple jurisdictions Allow comparison of BAU and a set of alternative scenarios change in land use pattern given smart growth choices
Character Area Types General Urban Suburban Conservation BAU TYPES Rural Urban Core TOD Traditional Town Center Village Center Activity Center Employment/ Industrial Center
BAU Scenario: Character Area Types General Urban Suburban Rural Urban Core Traditional Town Center Village Center Activity Center Employment/ Industrial Center
BAU Scenario: Future Land Use Policy Agricultural, Open Residential *GENERALIZED CATEGORIES Non-Residential Single Use Mixed-Use
BAU Scenario: Existing Development *existing development plus public open spaces, cemeteries, and parks
BAU Scenario: Development Constraints
BAU Scenario: Land Supply
BAU Scenario: Land Supply More Density SUPPLY CAPACITY: ALLOWABLE DENSITY Less Density
BAU Scenario: Suitability Factors Not Shown: Hospitals, Slopes and Environmental Features, Base Year Land Values
BAU Scenario: Development Suitability More Suitable Less Suitable
BAU Scenario: Residential Allocation Existing Development & Constraints Available Land Supply
BAU Scenario: Residential Allocation Existing Development & Constraints Future Residential Available Land Supply
BAU Scenario: Residential Allocation More Units *2009-2035 Residential Allocation Units per Parcel Less Units
BAU Scenario: Residential Density EXISTING RESIDENTIAL Units per ACRE More Units Less Units
BAU Scenario: Residential Density *2035 EXISTING + FUTURE Units per ACRE More Units Less Units
BAU Scenario: Residential Density *2035 FUTURE RESIDENTIAL NET NEW Units per ACRE More Units Less Units
Pros vs Cons: BAU BAU Pros future growth planned within defined urban growth boundaries cities and towns have plans to enhance urban centers established sense of community and place Cons utility policies allow an undesirable pattern of growth outside cities and towns, leads to higher costs for infrastructure and services bedroom communities with limited housing choices, lack balanced tax base lack of overall vision for protecting agriculture, open space, environmental assets low density, dispersed growth along corridors limits potential for viable transportation options

Alternative Scenario Concepts Four alternative scenario themes Conservation Compact Development Centers and Corridors Centers Themes used to develop concepts Concepts exaggerated to show emphasis toward a particular smart growth choice
Conservation Emphasis on set asides including open space and environmental assets forming contiguous greenbelts that may extend within and surround a regional center, growth is concentrated within remaining areas not set aside
Conservation
Pros vs Cons: Comparing Alternatives Conservation Pros designating agriculture, open space, environmental assets first ensures areas are protected at the start from encroaching and future growth Cons growth may continue to spread across the landscape in an undesirable pattern between areas conserved private property rights issues if land owners restricted from ability to convert land to more intensive uses (residential or commercial uses) higher infrastructure costs if undesirable pattern of growth occurs between areas conserved
Compact Development Urban growth boundary or service boundary, concentrated growth around regional center
Compact Development
Compact Development concentrated growth reinforces established regional center, economic benefits efficient use of infrastructure and services as growth is designated near existing infrastructure and services opportunity for coordinated services can protect countryside from sprawl could lead to leapfrog development and sprawl outside specified area for urban growth in nearby municipalities open space treated as a remnant as defined boundary, determined first, separates urbanized area from the countryside private property rights issues for land owners outside of boundary restricted from ability to convert land to more intensive uses reduced land availability adds pressures potential impacts to established neighborhoods resulting from targeted infill and redevelopment at higher densities
Centers and Corridors Growth concentrated into regional, urban and outlying village centers with remnant countryside areas forming greenbelts surrounding centers
Centers and Corridors
Centers and Corridors emphasis of concentrated growth along corridors, centers supports multiple transportation modes housing types that accompany centers and corridors development pattern provide greater housing choices efficient use of infrastructure and services as growth is designated near existing infrastructure and services opportunity for coordinated services may allow continued growth in an undesirable pattern between centers and corridors and impacts to countryside open space treated as a remnant as defined boundary, determined first, separates urbanized area from the countryside
Centers Growth concentrated into regional, urban and outlying village centers with remnant countryside areas forming greenbelts surrounding centers
Centers
Centers serves places with unique or individual identities, character competition among centers in a region duplication of services for multiple centers, can lead to higher costs for infrastructure some outlying centers become bedroom communities, lack balanced tax base while linkages exist, may not adequately support multiple transportation options within a region as centers are segregated from regional and other centers open space treated as a remnant as each center first defines its boundary separating urbanized area from the countryside

Comparing Alternatives Different futures exist given a shift in planning philosophy toward a theme Each has its own advantages and disadvantages Additional concepts and hybrids exist Preferred concepts to develop?
